[0026] The blanking component 4 is arranged on the material limiting component 3, and the blanking component 4 is used for discharging the waste mortar of the solar silicon wafer cutting fluid inside the material limiting component 3.

There are two second racks 46 in total, and the two second racks 46 are symmetrically arranged on both sides of the second gear 47. In the initial state, the second baffle 42 is in contact with the side wall of the drying box 31, and the pulling block 43 is located inside the second baffle 42, making the overall device function more complete to meet the actual use requirements.

[0027] Working principle: The drying box 31 is fixed on the material receiving hopper 2, and a hole for discharging the waste mortar of the solar wafer cutting fluid is provided through the bottom of the drying box 31. The rotating shaft 33 fixed with the stirring paddle 38 rotates inside the drying box 31. The top plate 32 is fixed on the top surface of the drying box 31. The first baffle 34 is slidably arranged on the top plate 32 and is also threadedly connected to the lead screw 35 rotating on the top plate 32. Therefore, after the lead screw 35 rotates, the first baffle 34 will slide to cover or open the hole reserved on the top plate 32. The sliding seat 36 slides on the drying box 31 and is further connected to the drying box 31 by the first spring 37. The first rack 39 fixed on the sliding seat 36 meshes with the first gear 310 rotating on the drying box 31. The first gear 310 and the differential gear set 312 can rotate together under the connection of the first transmission shaft 311. The worm 314 is driven by the pulley group 313 and the differential gear set 312. The worm 314 and the worm gear 315 fixed on the second transmission shaft 316 are in a threaded transmission connection relationship. The first bevel gear 317 fixed at the other end of the second transmission shaft 316 meshes with the second bevel gear 318 fixed on the lead screw 35. Therefore, after the waste mortar of the solar wafer cutting fluid is placed inside the drying box 31, as the weight increases, the entire sliding seat 36 slides downward, and the first rack 39 will drive the first gear 310 to rotate. Under the joint drive of structures such as the first transmission shaft 311, the differential gear set 312, the pulley group 313, the worm 314, the worm gear 315, the second transmission shaft 316, the first bevel gear 317, and the second bevel gear 318, the lead screw 35 is driven to rotate together, and then the first baffle 34 starts to slide. When the waste mortar of the solar wafer cutting fluid inside the drying box 31 reaches a certain amount, the sliding seat 36 drops to the lowest position, and the first baffle 34 will completely cover the missing part of the top plate 32 to ensure that the amount of each filtration and screening does not exceed the working range of the circular sieve machine 1. At this time, start the electric heating wire inside the drying box 31 and rotate the rotating shaft 33 to make the stirring paddle 38 stir the waste mortar of the solar wafer cutting fluid inside it to accelerate the removal speed of the moisture contained in the waste mortar of the solar wafer cutting fluid.

[0028] The second baffle 42 slides on the sliding seat 36, and the pulling block 43 slides on the second baffle 42 and is also connected to it by the second spring 44. The stop block 41 slides on the drying box 31 and is also connected to it by the third spring 45. When the sliding seat 36 drops to the lowest position, the pulling block 43 protrudes from the surface of the second baffle 42 and contacts the stop block 41 under the action of the second spring 44. By adjusting the position of the stop block 41, the pulling block 43 can protrude from the surface of the drying box 31. At this time, the second baffle 42 can be pulled through the pulling block 43. At the same time, the second gear 47 rotates on the sliding seat 36 and meshes with the second rack 46, and the second rack 46 is also fixed on the second baffle 42, asFigure 6 The positional relationship shown. Therefore, when pulling the second baffle 42 on one side, it will cause the second baffle 42 on the other side to slide in a certain direction to expose the notch. The quantified and dried waste mortar is put into the inside of the circular sieve machine 1 through the material receiving hopper 2 for filtering and screening. After the feeding of the waste mortar of the solar silicon wafer cutting fluid in the drying box 31 is completed, the pull block 43 is pushed back to place it inside the second baffle 42. Under the action of the third spring 45 and the first spring 37, the whole structure will return to the initial state for the next use.
